Perfection

Something that caught my eye after reading Chapter one again out of boredom was "We are unfinished and impressible, and in need of constant modeling to achieve our ultimate end of moral perfection " (13). Now this got me thinking of what is perfection because we all believe that being perfect without flaw but yet we as humans are constantly trying to be perfect morally. I don't know if that makes sense or not because why would we try to obtain something when we know it's impossible to achieve perfection? Wouldn't we just be selfish people trying to aim for a star no matter how hard we try we won't get it. I was also thinking about how we are unfinished which makes me wonder about Confucius and if he was able to reach that point of perfection or understanding?
